ENH: Reset BRAINSTools to build without the ITK_FUTURE_LEGACY_REMOVE

The inconsistent use of ITK_FUTURE_LEGACY_REMOVE was causing major runtime
errors with regards to virtual functions being located in different places
in the object files between compilation units.

This update also turns off many new tools that are not ready for
distribution with Slicer.
